docker-development

Docker and container development agent skill and plugin for Dockerfile optimization, docker-compose orchestration, multi-stage builds, and container security hardening. Use when: user wants to optimize a Dockerfile, create or improve docker-compose configurations, implement multi-stage builds, audit container security, reduce image size, or follow container best practices. Covers build performance, layer caching, secret management, and production-ready container patterns.

Quality

Content

71%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

Highly actionable content with executable multi-stage patterns, decision trees, and concrete security fixes, weakened by redundancy across sections, dated version pins, and references to scripts that are absent from the bundle.

Suggestions

De-duplicate the optimization rules that appear in both the /docker:optimize checklist and the Proactive Triggers section so each appears once.

Ship the referenced scripts (scripts/dockerfile_analyzer.py, scripts/compose_validator.py) in the bundle, or remove the references and inline a small validation snippet so workflows are self-contained.

Move pinned versions (golang:1.22, node:20, python:3.12) into a version table or note that users should pin current tags, to keep examples from dating the skill.

Dimension	Reasoning	Score
Conciseness	The body is mostly dense, useful guidance (decision trees, checklists, code) rather than concept explanation, but repeats checklist items across 'Workflow' and 'Proactive Triggers' and embeds dated version pins (golang:1.22, node:20, python:3.12) outside any deprecated section, which the rubric penalizes.	3 / 5
Actionability	Provides copy-paste-ready, executable Dockerfile patterns for Go/Node/Python, concrete CLI invocations with flags, and a security table with specific fixes (USER nonroot, --mount=type=secret, cap_drop: [ALL]) covering common cases.	5 / 5
Workflow Clarity	Each slash command has a numbered sequence and the optimize workflow includes an explicit 'Validate' checkpoint, but the compose and security workflows lack validation/feedback loops and the referenced analyzer script is not present in the bundle.	4 / 5
Progressive Disclosure	Well-sectioned with clear headers, but the entire skill is inlined in SKILL.md and references scripts/dockerfile_analyzer.py and scripts/compose_validator.py that do not exist in any bundle directory, leaving references pointing to missing files.	3 / 5
	Total	15 / 20 Passed

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that clearly states capabilities and provides an explicit 'Use when' trigger list with natural phrasing. It is comprehensive and distinct with only minor gaps in trigger synonyms.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Dockerfile optimization, docker-compose orchestration, multi-stage builds, and container security hardening' plus 'reduce image size' — giving comprehensive, specific coverage rather than vague claims.	5 / 5
Completeness	Explicitly answers both 'what' (optimization, orchestration, multi-stage builds, hardening) and 'when' via a concrete 'Use when:' clause with multiple trigger phrases, matching the top anchor.	5 / 5
Trigger Term Quality	The 'Use when' clause surfaces natural phrases users say ('optimize a Dockerfile', 'docker-compose', 'multi-stage builds', 'reduce image size'), with good synonym coverage; a few natural variants like 'Docker build is slow' or 'containerize' are absent.	4 / 5
Distinctiveness Conflict Risk	Docker/container-specific niche with distinct triggers (Dockerfile, docker-compose, container, image size) and minimal overlap with unrelated skills.	5 / 5
